A Stochastic Broadcast Pi-Calculus [PDF]

open access: yes, 2011
In this paper we propose a stochastic broadcast PI-calculus which can be used to model server-client based systems where synchronization is always governed by only one participant. Therefore, there is no need to determine the joint synchronization rates.
